    PURPOSE: To describe the pattern of uveitis among Chinese, Malays, and Indians at a tertiary referral institution in Singapore.

    METHODS: Charts between January 1997 and December 2010 were retrospectively reviewed. Charts between January 2014 and December 2014 were prospectively reviewed.

    RESULTS: A total of 1249 and 148 charts were retrospectively and prospectively reviewed, respectively. The top causes of anterior uveitis (AU) were HLA-B27, idiopathic, and CMV AU. The top known causes of intermediate uveitis were tuberculosis, primary intraocular lymphoma, and sarcoidosis. The top causes of posterior uveitis were CMV retinitis, toxoplasmosis, and dengue maculopathy. The top causes of panuveitis were VKH, idiopathic panuveitis, tuberculosis, and Behçet disease. HLA-B27 and CMV AU were more frequent among Chinese (21% vs 9% (non-Chinese); p<0.001; 10% vs 5% (non-Chinese); p<0.001, respectively). Tuberculous uveitis was more frequent among Malays and Indians (12% (non-Chinese) vs 5% (Chinese), p<0.001).

    CONCLUSIONS: Different uveitis patterns were encountered among patients of different races.

    Purpose: To standardize a nomenclature system for defining clinical phenotypes, and outcome measures for reporting clinical and research data in patients with ocular tuberculosis (OTB).Methods: Uveitis experts initially administered and further deliberated the survey in an open meeting to determine and propose the preferred nomenclature for terms related to the OTB, terms describing the clinical phenotypes and treatment and reporting outcomes.Results: The group of experts reached a consensus on terming uveitis attributable to tuberculosis (TB) as tubercular uveitis. The working group introduced a SUN-compatible nomenclature that also defines disease "remission" and "cure", both of which are relevant for reporting treatment outcomes.Conclusion: A consensus nomenclature system has been adopted by a large group of international uveitis experts for OTB. The working group recommends the use of standardized nomenclature to prevent ambiguity in communication and to achieve the goal of spreading awareness of this blinding uveitis entity.
  3. The Collaborative Ocular Tuberculosis Study (COTS) Consensus (CON) Group Meeting Proceedings

    An international, expert led consensus initiative was set up by the Collaborative Ocular Tuberculosis Study (COTS) group to develop systematic, evidence, and experience-based recommendations for the treatment of ocular TB using a modified Delphi technique process. In the first round of Delphi, the group identified clinical scenarios pertinent to ocular TB based on five clinical phenotypes (anterior uveitis, intermediate uveitis, choroiditis, retinal vasculitis, and panuveitis). Using an interactive online questionnaires, guided by background knowledge from published literature, 486 consensus statements for initiating ATT were generated and deliberated amongst 81 global uveitis experts. The median score of five was considered reaching consensus for initiating ATT. The median score of four was tabled for deliberation through Delphi round 2 in a face-to-face meeting. This report describes the methodology adopted and followed through the consensus process, which help elucidate the guidelines for initiating ATT in patients with choroidal TB.
